SHIP.

SPECIFICATION forming part of Letters Patent No. 550,580, dated Becember 3, 1895.

' Application filed Apri14, 1895. Serial No. 544,403. (No model.)

To all whom it may concern.-

Be it known that I, J ULIUs BLUEMEL, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented a new and useful Ship, of which the following is a specification.

My invention relates to an improvement in ships or such vessels driven or propelled through water, in which a flanged or spiralshaped hull, revolves on a stationary center or pivot.

The object of my improvementis to increase the ordinary maximum speed of ships propelled through water by obviating all unnecessary resistance or friction against the wa ter when being thus propelled, thus accomplishing an increase in velocity or speed. I attain this object by means of the mechanism and combination of mechanism illustrated in the accompanying drawings, in which- Figure l is a side elevation representing my device in position in the water. Fig. 2 is a longitudinal. section of the hull B of Fig. 1, showing interior arrangement. Fig. 3 is a cross-section through hull B of Fig. 1. Fig. 4 is an end view of Fig. 1.

Similar letters refer to similar parts in the different Views.

A is a toothed pinion.

B is a bottle-shaped revolving hull.

B is a spiral flange on the'exterior of hull B. B is an internal gear-wheel fastened on the interior of hull B. O C are openings and exits from the interior of hull B.

D is a stationary platform or floor in the interior of hull B.

E is a stationary hollow central shaft on which hull B revolves and to which platform or floor D is rigidly connected.

F is a suitable motor or engine for eifecting the rotation of hull B.

G G are openings in E for ventilating purposes and for ingress and egress to and from interior of vessel or ship.

11 is a suitable propeller rigidly connected to hull B, thereby revolving with it.

I is a suitable rudder for steering or directing the course of the ship; I, attaching device to rudder I for eifecting its operation from interior of ship.

J is a lookout or signal bridge overhead of ship, rigidly connected to upper outer ends of E and thereby comparatively stationary.

The operation of my device is as follows: The motor or engine F being driven and set in motion through suitable means causes the rotation of pinion A by means of its connection therewith, which, in turn, meshes into and gives motion to the internal gear B which is connected and fastened on interior of hull B, and thereby causing hull B to revolve around the central journal or axis shown here as a hollow shaft E. Connected to hull B in suitable position on its exterior and concentric therewith is a suitable propeller H, revolving with it and causing the propulsion or passage of the ship through the water. Around the exterior of hull B and rigidly connected thereto is a spiral-shaped flange which, when the hull B revolves, acts as a screw, decreasing the friction or resistance of the water and thereby facilitating the passage of the vessel or ship through the water and consequently increasing its speed. To further facilitate this passage and increase of speed, hull B, with its exterior spiral flange'B, is

preferably made tapering lengthwise and of inclosed circular section, as shown, and water-tight. The hollow shaft E is made comparatively stationary by its being weighted or overbalanced below its center by hanging weight and mechanism rigidly connected to it and as low as practicable in the interior of revolving hull B to admit and allow of its ends and exits C and 0 remaining under these conditions in a comparatively vertical and upright position. Attached to these upper ends C and G of E, and connected longitudinally across from O to C, as shown, is alightconstructed bridge or railing for purposes which are obvious, though not material, being a matter of mere construction and convenience.

The rudder I, journaled in position at one end of stationary shaft E, maybe operated in any suitable manner, the mechanism shown here being an endless chain passing around a chain-wheel on spindle of rudder along the interior of hollow shaft E, through the opening G in E, to a Windlass or device suitable to eifect the motion of said rudder I, allow ing the ship to be steered in any direction.

The propeller H driven, as shown, can be operated independent from hull B, if found advisable, in any suitable manner from interior of ship.

The openings G and G are to allow for ingress and egress through hollow shaft E, and also for ventilation for interior of ship by means of the comparatively-s11stained vertical position of E and open ends or exits C and C.

Suitable devices (not shown) and means for conveniently effecting the ingress and egress through E and the interior of B, are matters of mere construction and not necessary to be shown,they not being an essential feature, 'consisting,probably, in ladders ,stairs,or ropeladders, &c., leading up to the exits G and C. To conveniently allow for this ingress and egress, the hollow shaft E is made of such a size or diameter in cross-section as to easily allow a person or persons to pass along its interior and entire length to the exits at C and C, but, if necessary, may be made larger in cross-section for the purposes not herein mentioned.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a ship, the water tight hull B, tapering longitudinally as shown, having an exterior spiral flange B fastened to it and an internal gear B fastened around its interior, pinion A and engine F suitably located in stationary position on platform or floor D, the stationary, hollow, central-shaft E having openings G and G located inside of hull B and terminating in upright position above Water line or level and having exits C and O as shown, bridge or railing J fastened and supported from ends 0 and C 011 E, propeller H fastened to hull B, rudder I and its operating mechanism 1, all shown and operating, sub stantially as described.

JULIUS BLUEMEL.
